I remember once in a Utah canyon seeing a cliffside with a wide hollow about halfway up. It was a shallow depression - perhaps a yard deep, but a large tree had managed to take root in the rock, and unable to grow upward, had spread sideways, and also outward from the cliff face. It's precarious perch was evoked by this piece.

I am glad to have revived a vision in your memory. Mine was of a dying tree, bleached white by the sun, and hanging on the edge of a cliff on Lake Sam Rayburn....
